Average Private School Tuition in California (2026)

Why California Private School Tuition Is So High

Three things push California above the national average. First, land and facility costs: a private school building in Los Angeles or Palo Alto costs far more per square foot than the same building in Mississippi. Schools pass those costs to families. Second, teacher salaries in California track the general cost of living — a teacher who could earn $75,000 at a New England prep school needs $95,000+ to afford a Bay Area apartment. Third, California has a high concentration of independent nonsectarian schools, which run about 40% above national independent averages.

Religious schools are cheaper — and California has plenty of them. The state has over 400 Catholic high schools alone. If your priority is private education at a manageable cost, a Catholic or Christian school in the Inland Empire or Central Valley can run $7,000–$12,000/year.

Average Private High School Tuition in California

Private high school in California averages $24,200/year statewide. That's the figure across all school types. Break it down: religious high schools average around $12,400; independent high schools average about $41,400. The range runs from $9,000 at a Catholic school in Fresno to $48,000+ at elite independent schools in LA and the Bay Area.

Southern California private high school tuition specifically averages $27,800 — the LA market skews it up. Bay Area private high school averages $42,000, driven by the density of independent schools in San Francisco, Marin, and the Peninsula.

Average Private Middle School Tuition in California

Private middle school costs $19,800/year on average statewide. Middle school is priced near each school's baseline, so these numbers track closely with the all-grades average. Bay Area middle schools average $34,200; Southern California averages $22,900; Sacramento and the Central Valley are significantly cheaper at $9,000–$14,000.

One thing worth knowing: many California private schools are K–12 or K–8, meaning middle school families rarely face a separate admissions process. Tuition still steps up from elementary, but you're often staying in a school you already know.

How California Compares to Other Large States

California's $19,800 statewide average is roughly double Texas ($10,200) and triple Mississippi ($6,450). New York ($22,400) and Massachusetts ($22,800) are the only states that come close to California's upper range. Florida ($13,200) and Illinois ($15,800) fall between California and the national average.

The Bay Area specifically competes with Manhattan and Boston's Back Bay for the most expensive private school market in the country. Outside those markets, private school in California — particularly at religious schools in inland areas — costs significantly less than coastal California headlines suggest.
